[PLUG] boot failure

Thanks for the information.  I have been running the system on the dvd for
a number of hours without incident.  I just ran sudo fsck.ext4 -fv
/dev/sda1.  There were a number of errors, but nothing which looked very
serious to me.  (All errors corrected.)  I should have captured the reports
to a file, but instead I took two photos. Errors were inodes part of a
corrupted linked list, inode w/zero dtime, block bitmap differences, free
blocks count wrong, inode bitmap differences, free inodes count wrong.
There were no bad blocks.  If the details are important I expect I can get
the photos up.

I should point out that this HD is new as of August, as is the OS (ubuntu
14.04 replacing 12.04).

Assuming I have been hacked, how do I recover?  (I have not tried to reboot
since running fsck.)

Thanks again for your advice.

-Denis
